- the reservation means of transportation satisfying the patterns P3 and P7 in Fig. 2 that is, a means of transportation with reserved seats and vacant seats, and having route search conditions other than seat conditions. It shows that a satisfactory means of transportation should be extracted.
- the input route search condition is sent to the vacant seat route search device 30.
- the route search means 36 refers to the reservation information DB 51 and the operation data DB 52 and does not satisfy the route search condition including the seat condition! ⁇ ⁇
- Excluding traffic means that is, operation data of transportation means satisfying the route search conditions including the seat conditions is extracted from the operation data DB 52, and operation network data based on the operation data is extracted as operation data for search.
- Route search is performed after forming in DB37.
- the route search means 36 refers to the reservation information DB 51 and the operation data DB 52 so as not to extract a means of transportation that does not match the route as a route. Even if there are no vacant seats, only those that meet the route search conditions are extracted, and the route is searched by forming the operation network data in the search operation data DB37. Therefore, those with no reserved seats such as local lines are excluded.
- the route to the transportation system with designated seats will be allocated on foot or by car (taxi). Or, for air routes where the departure and destination are airports, if there are vacant seats, the seat conditions are selected.
- the route search by the route search means 36 is performed as follows. In other words, if the departure point or destination is not a terminal such as a station or airport, but any point, it is possible to get on the transportation from the departure point in the same way as a general pedestrian navigation system. Stations of several destination candidates in the vicinity of the destination are searched, and the shortest route from each candidate station to the starting point and the shortest route from the destination station to the destination are searched as the respective guide routes. Is done. Then, the route search means 36 refers to the reservation information DB 51 and the operation data DB 52, extracts the operation data of the means of transportation that matches the route search conditions, and based on the extracted operation data! /, The search operation data DB 37 Then, a dynamic operation network data from each departure candidate station to the destination candidate station is formed to search for a plurality of candidate routes (candidate means of transportation).
- operation data (generally also referred to as an operation diagram) of transportation means to be searched for a route is first extracted.
- a route search condition including a seat condition. Only the means of transportation that matches the conditions are extracted. For example, in the case of the “complete reservation” seat condition described above, only the means of transportation of patterns P3 and P7 in FIGS. 2 and 4 are extracted. Since the operation data DB52 only stores information such as the availability of free seats and reserved seats for each means of transportation, the availability of seats is obtained from the reservation information DB51.
- the method described in Non-Patent Document 1 described above is used for the formation of the operation network data in the operation data DB for search and the route search using the operation network data.
- Reservation information DB51 constantly updates the reservation status of each means of transportation (train, aircraft, etc.) operated by each transportation facility 60-6N. Reservation information
- the data structure of DB51 is as shown in Fig. 5, taking a train as an example. First, there is a train ID, and this ID is followed by all periods that can be reserved from today (Today). The reservation status data is sequentially updated and accumulated. Reservation status data is stored in four types of reservation status data: “Type A—NS”, “Type A—S”, “Type GN S”, and “Type G—S” for each train. Is done.
- Type A—NS is a non-smoking seat for a regular car
- Type A—S is a smoking seat for a regular car
- Type G—NS is a non-smoking seat for a Darine car
- Type G — “S” stores reservation status data for smoking seats in reserved seats on green cars.
- Reservation status data B1 to B32 for each seat type "type A-NS", “type A-S”, “type G-NS”, and “type G-S” are stored in 32 bits.
- Bit B1 stores the presence / absence of reservation at the starting station, and stores the presence / absence of reservation at each stop station in sequence up to Bits B2-B32.
- the reservation status is stored as “1” or “0” in each bit. “1” indicates that the seat is full and there is no vacancy, and “0” indicates that the seat is not full and there is a vacancy.
- the reservation status data of one seat type is composed of 32-bit data as described above, and the first bit (LSB) indicates the reservation status at the first station, that is, whether or not the seat is full. Represents. Full seats are "1".
- the next bit stores the reservation status at the next stop. Since the data length is 32 bits, the reservation status for 32 stations including the first station can be stored. In Japan, it is long enough. If there are more stops, the data length can be configured with an appropriate length such as 64 bits or 128 bits. If there are few stop stations, “0” should be stored in unnecessary upper bits. Via in case of aircraft Since there are not so many places, a data length of 16 bits or 8 bits is sufficient.
- the boarding section in boarding section data (B) is recorded as “1” in the section corresponding to one station before the boarding station from the boarding station (the boarding station may be fully occupied by the boarding station force) Data, created based on route search conditions (boarding station and getting-off station). If the data (C) that results from ANDing this data becomes “0”, the seat is not fully occupied. If the result is not “0”, “1” is recorded in some bit, which means that there is a full seat in the boarding section.
- the route search means 36 performs the above processing and extracts only the means of transportation (individual trains, aircraft, etc.) that match the route search conditions including the seat conditions.
- the route search for the entire operation network is shorter. You will be able to search for the desired route efficiently in time.
- Reservation information DB51 should reflect the reservation status of each transportation facility 60-6N in real time, but reservations often fluctuate between the ticket sale date, the boarding date, and about two days before that. Therefore, it is preferable to collect the reservation status corresponding to that period at a particularly short interval and reflect it in the database.
- operation data DB52 and reservation information D should reflect the reservation status of each transportation facility 60-6N in real time, but reservations often fluctuate between the ticket sale date, the boarding date, and about two days before that. Therefore, it is preferable to collect the reservation status corresponding to that period at a particularly short interval and reflect it in the database.
